RE: Date Tracking Query

You had a semicolon at the end of the FROM statement - a semicolon only goes
at end of SQL.
You had an extra closing parenthesis and missing one opening parenthesis.
Try this --
SELECT [tblvehicles].[Comm Number]
FROM tblvehicles LEFT JOIN tbldispatch ON tblvehicles.VechID =
tbldispatch.VechID
GROUP BY [tblvehicles].[Comm Number]
HAVING ([tbldispatch].[VechID] Is Null) OR (Max([CheckOut]) Is Not Null AND
[CheckIn] Is Not Null) OR ([EstRtn] <= CVDate([Enter date-time wanted]) AND
[CheckOut] Is Not Null);

When I correct all the fields I get this error at the HAVING clause.

The LEVEL clause includes a reserved word or argument that is misspelled or
missing, or the punctuation is incorrect. (Error 3136)

Any ideas what might cause this?

Thanks again

I did not see VechID in your query from tblVehicles so I guesed.

Im kinda on to this but I was wondering where in the join expression is the
Commission Number field for the "DisPatch" table coming from. I keep getting
Syntax error in that statement and I do not have a Commission Number field in
table dispatch I am only using the VechID field.

I did not have the field names you used so you need to substitute mine for
yours --

SELECT [tblVehicles].[Commission Number]
FROM tblVehicles LEFT JOIN Dispatch ON [tblVehicles].[Commission Number] =
[Dispatch].[Commission Number]
GROUP BY [tblVehicles].[Commission Number]
HAVING ([Dispatch].[Commission Number] Is Null) OR (Max([CheckOut]) Is Not
Null AND [CheckIn] Is Not Null)) OR ([EstRtn] <= CVDate[Enter date-time
wanted]) AND [CheckOut] Is Not Null)

1- ([Dispatch].[Commission Number] Is Null) == Never been dispatch.
2- OR (Max([CheckOut]) Is Not Null AND [CheckIn] Is Not Null) == Dispatched
but has been returned.
3- OR ([EstRtn] <= CVDate[Enter date-time wanted]) AND [CheckOut] Is Not
Null) == Out but due back on or before need.

In might lie my problem with my query I DO have TWO tables and my query is
definitely messed up I am unsure how to write both tables in

"KARL DEWEY" wrote:

What I posted as a suggestion was TWO tables - Vehicles & Dispatch.
Your query indicates you made it all one table.

I tried intergrating the one from the previous poster with variations

SELECT [Commission Number]
FROM tblVehicles
WHERE #08/03/2009 14:50:00# <=[CheckOut]
AND (#08/03/2009 14:50:00# >=[CheckIn]
Or [CheckOut] Is Null)

My thinking was if I inversed the less than greater than it would give me
everything not already checked out. I have something wrong somewhere because
it keeps asking for my input. I am pretty novice at SQL building I have only
done a handfuls. Thanks for helping me

I agree with the table desing you have suggested and I went ahead and created
it that why but now I am having difficulties writing the query for it. It
keeps asking for my to input the values for vehicle number and I do not that
to occur. When someone requests a vehicle I want to run the query and only
ask for a check out date to find what vehicles are available

At 08/03/09 2:50 the data for 64219 would not look like this -- 08/03/09
12:00 pm 08/03/09 3:00 pm as it has not returned at that time.

You should have a table with the vehicles and their information with a
second table for dispatching and related as one-to-many.
Vehicles --
VechID - Autonumber - primary key
VechNum - text
Type - Sedan 2Dr
Make - Prexous
Year - 1994
etc.

Dispatch --
DisptID - Autonumber - primary key
VechID - number - long integer - foreign key
CheckOut - DateTime
CheckIn - DateTime
EstRtn - DateTime
Driver -
Purpose -

Sorry about that. I have a table "tblvehicles" with fields as described below
[Vehicle Number],[Date Assigned],[Time Assigned],[Date Returned],[Time
Returned]

sample records of vehicles checked out and this information is in the
"tblvehicles"
64202 08/03/09 7:00 am 08/03/09 2:00 pm
64219 08/03/09 12:00 pm 08/03/09 3:00 pm
64077 08/03/09 7:00 am 08/03/09 9:00 am

What I am trying to accomplish is to run a query of some sort that will give
a list of which vehicle numbers are available at the time of the run query
that are not checked out. In this case if the query was ran on 08/03/09 2:50
pm vehicle 64202 and 64077 should be returned in the query.

I'm not sure how you can have "unique vehicles" with multiple times a day.
Please provide table, query, and field names with some sample records.

Hint: when you get a reply with "can we assume", it generally begs you to
provide greater detail so we don't have to "assume".

my table is setup to only have unique vehicles but each vehicle can be
checked out multiple times a day so there is part of my confusion not to
create duplicates

"Duane Hookom" wrote:

Can we assume you have a table of unique vehicles? Can we assume your
returned fields always have values for expected returns? Can we assume your
query name is qryNoName?

Try something like:

SELECT tblVehicles.*
FROM tblVehicles
WHERE [Vehicle Number] NOT IN
(SELECT [Vehicle Number]
FROM qryNoName
WHERE Now() Between [Date Assigned] + [Time Assigned] AND [Date Returned]
+ [Time Returned])

I am working on vehicle tracking database and I have a query with these fields

Vehicle Number Date Assigned Time Assigned Date Returned Time
Returned


How can I create a function that will tell me what vehicles are available at
the time the query is opened for assignment so I do not create a duplicate. I
have 12 unique vehicle numbers to choose from. I have tried unmatched query
and several different functions but nothing is working. Please help! Thanks
